springboot 2.0 使用redis
阿新 • • 發佈:2019-01-25
由於還使用elasticsearch,所以使用jedis沒有使用lettuce
1.pom引入
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
<exclusions>
<exclusion>
<groupId>redis.clients</groupId >
<artifactId>jedis</artifactId>
</exclusion>
<exclusion>
<groupId>io.lettuce</groupId>
<artifactId>lettuce-core</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency >
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
</dependency>
2.配置走一波,2.0版本之前的一些被移除了,我使用jedis就配置jedis了,使用lettuce的話一個樣,換個名字就行
# Redis_config
# Redis資料庫索引(預設為0)
spring.redis.database=3
# Redis伺服器地址
spring.redis.host=127.0.0.1
# Redis伺服器連線埠
spring.redis .port=6379
# Redis伺服器連線密碼(預設為空)
spring.redis.password=
# 連線超時時間(毫秒)
spring.redis.timeout=3600
# 連線池最大連線數(使用負值表示沒有限制)
spring.redis.jedis.pool.max-active=8
# 連線池最大阻塞等待時間(使用負值表示沒有限制)
spring.redis.jedis.pool.max-wait=-1
# jedis超時
spring.redis.jedis.shutdown-timeout=100
# 連線池中的最大空閒連線
spring.redis.jedis.pool.max-idle=8
# 連線池中的最小空閒連線
spring.redis.jedis.pool.min-idle=0
3.redis config走一波
package cc.datebook.config;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.interceptor.KeyGenerator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import java.lang.reflect.Method;
import java.util.HashSet;
import java.util.Set;
/**
* Redis快取配置類
* @author wangH
*
*/
@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {
@Autowired
private JedisConnectionFactory jedisConnectionFactory;
/**
* @description 自定義的快取key的生成策略
* 若想使用這個key 只需要講註解上keyGenerator的值設定為keyGenerator即可</br>
* @return 自定義策略生成的key
*/
@Bean
public KeyGenerator keyGenerator() {
return new KeyGenerator(){
@Override
public Object generate(Object target, Method method, Object... params) {
StringBuffer sb = new StringBuffer();
sb.append(target.getClass().getName());
sb.append(method.getName());
for(Object obj:params){
sb.append(obj.toString());
}
return sb.toString();
}
};
}
//快取管理器
@Bean
public RedisCacheManager cacheManager(JedisConnectionFactory jedisConnectionFactory) {
return RedisCacheManager.create(jedisConnectionFactory);
}
/**
* RedisTemplate配置
*
* @param jedisConnectionFactory
* @return
*/
@Bean
public RedisTemplate<String, Object> redisTemplate(JedisConnectionFactory jedisConnectionFactory ) {
//設定序列化
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);
//配置redisTemplate
RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
redisTemplate.setConnectionFactory(jedisConnectionFactory);
RedisSerializer stringSerializer = new StringRedisSerializer();
redisTemplate.setKeySerializer(stringSerializer);//key序列化
redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);//value序列化
redisTemplate.setHashKeySerializer(stringSerializer);//Hash key序列化
redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);//Hash value序列化
redisTemplate.afterPropertiesSet();
return redisTemplate;
}
}
4.jedis config 走一波
package cc.datebook.config;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;
@Configuration
public class JedisRedisConfig {
@Value("${spring.redis.host}")
private String host;
@Value("${spring.redis.password}")
private String password;
@Value("${spring.redis.port}")
private int port;
@Value("${spring.redis.timeout}")
private int timeout;
@Value("${spring.redis.jedis.pool.max-idle}")
private int maxIdle;
@Value("${spring.redis.jedis.pool.max-wait}")
private long maxWaitMillis;
@Bean
JedisConnectionFactory jedisConnectionFactory() {
JedisConnectionFactory factory = new JedisConnectionFactory();
factory.setHostName(host);
factory.setPort(port);
factory.setTimeout(timeout);
factory.setPassword(password);
return factory;
}
@Bean
public JedisPool redisPoolFactory() {
JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
jedisPoolConfig.setMaxIdle(maxIdle);
jedisPoolConfig.setMaxWaitMillis(maxWaitMillis);
JedisPool jedisPool = new JedisPool(jedisPoolConfig, host, port, timeout, password);
return jedisPool;
}
}
5.然後直接用就行了
@Autowired
private RedisTemplate redisTemplate;
HashOperations<String,String,String> hashOperations = redisTemplate.opsForHash();
